oall whom Ait may concern:

Be it known that I, OSCAR F. FALK, a citi zen of the United States, residing at Belleville, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Telephone Dictating Machines or Apparatus of which the following is a full, clear, and. exact description.

This invention relates to a class of apparatus employed for dictating telephonically from a central oliice'desk or station, select ively to any one of a corps of stenographers. Apparatus of this class forms the subject of prior Patents llos. 843,186 and 880,537 and which embody telephone instruments connected by circuits of such a character that the particular or special purposes of dictation are served'.

The present invention consistsoli' a dictograph apparatus having all the essential functions of the prior apparatus above re` ferred to, but in which' the construction is much more simple, and better adapted for the purposes, of manufacture and practical use.

Prominent among the features oli the present invention is the characteristic of accessibility of the various component parts or elclnents, and easy `renmvability and interchangeability ol' such parts.

Another feature ol the invention relates to means for making all the electrical con nections without the use of complicated cir cuit wiring.

A third object of the invention is to provide what I term a supplementall frame for the support of the operating keys or jacks and their connections, whereby the -latter can not only be removed, but are-always in condition to be inspected from any side or direction. A

With the foregoing and other objects in view my invention consists in the features of construction and combination as hereinafter set forth and claimed.

In the drawings: Figure 1 is a front elevation of a dictoraph apparatus embodying the principles otmy invention. Fig. 2 is a View of the same with the front of the casing removed. Fig. 3 is a top View with the 'top et the casing removed. I `i t is a gen- .shown in a di'erent position. Fig. 5 is a Spccicationef Letters Patent. Patented Allg?. 16,1910.'

Serial No. 507,320.

sectional view on the line IV-IV of Fig. 4L; and Fig. 6 is a detail View showing the manner in which the electrical connections are made between different keys.

`Referring to the drawings in. which like parts are designated'by the same reference sign, l denotes a box or casing of rectangu lar outline and 2 indicates what I shall term ra supplemental or skeleton frame and which I make in the form of an elongated square prism, preferably of metal running onl along the corners or outlines thereof. Eacli of the faces of such supplemental rismatic frame constitute a base on whic devices may be secured or mounted, extending between the side or edge bars thereof. Any device or object mounted inv this manner is accessible from all sides or directions through the various open faces of this prismatic' frame.

3 denotes operating keys which are com- -bined with visual signals 4 which may be considered as permanently assembled together forvthe purposes of the present ap li cation. Each such combined signal and liey has a fiat front plate 5 'which is secured at 6 to the edges of the front face of the prismatic frame 2. Under these circumstances, the signals and keys extend back into the `body or interior of said prisniatic trame.

7 denotes the protruding spring blades o'l' the key 3 and which project beyond the rear side or face of the prismatie irame 2.

8 designates an insulating bar preferably of hard wood which is fastened to extend along the lower part ot' the rear side of the prismatic frame 2. The rear face oi' this bar 8 has a series ot' `grooves therein which are quite narrow and deeply recessed into the n'latcrial of the strip.

l() denote metallic strips or ribbons l0- cated in the grooves 0 and extending along the length of the wooden bar. 'lhese rib bons constitute what may be termed busl bars and have an important. function 1n establlshlng the circuits ol the key. For this purpose the insulatingr bar 8 has a hole or i perforation 1Ql opposite cach of the keys 3, and Athrolugh which perforation the blades 7 protrude. The blades ol the key are initially bent by a forming die or fixture so that they fall automatically into registry with one of the bus-bars l0.

I have illustrated the connection of the spring blades with theI bus-bars at 13. The

particular features of this engagement constitute more particularly the subject of my companion application Serial No. 508,971 led herewith and are claimed therein. I shall not therefore set forth the features of this construction in greater detail in the present case. y

15 denotes a swinging instrument frame pivoted on the skeleton or prismatic frame 2 at the point 16 so as to swing in a horizontal plane corresponding to the top face of the prisrnatic frame 2. The swinging frame 15 preferably comprises an integral sheet metal stamping oi h-shaped outline with a prong 17 struck up on the small end or extremity.

19 denotes a U-shaped spring tongue or clip adjacent to the prong 1 7 and adapted to coperate therewith to engage a flat or disk receiver 20 of sensitive type.

21 indicates a curved horn extending from the receiver 2() and terminating in an enlarged orifice 22 in a plane at right-angles to the plane of the receiver 20.

24 designates a U-shaped spring tongue or clip fixed to the swinging frame 15 in a plane parallel `with that of the orifice This spring tongue 24 is adapted to receive a' transmitter 25 having a mouthpiece 26, with its inlet orifice in the plane the oriice 22 of the horn 21. This plane is so related to the pivot point 16 of the swinging frame 15 as to swing into coincidence with the front face ofthe skeleton frame 2 at a certain position of said swinging frame. This position corresponds to a coincidence of the prong 17 with a side face of the skeleton frame 2. The casing 1 is designed to tit the outline of the skeleton traine 2 closely on its front and side faces, thereby insuring that the transn'iitter and receiver orifices are l they are located close y adjacent to the front wall of the casing 1 in normal use as clearly shown in Fig. 3. In the wall of the casing at-tliis point I provide a turn-button 33 with a cam 34 adapted to bear downward on the upperspring blade 31 thereby establishing a contact.

The various electrical circuits ape estab- 'lished by iiexible connections from the receiver 20 and the transmitter 25 to the busbars 10.- All of the remaining electrical conneetions are established by the engagement of the key blades with the bus-bars; these circuits and features beine set forth in detail in my companion application above' rolerred to, will not require repetition in this case.
